Hi All,
My E6400 has been suffering overheating problems with the current hot weather (over 30C degrees). When the machine overheats it begun to throttle to 75% then to 35%. Once it reached 35% the machine is extremely slow (much slower than normal 35% in power saving mode), it like the machine is put in the safe mode and it won’t recover once the temperatures drops i.e. ACPI, & cpu =40’s & NVS160 = 60’s. The only thing fix the problem is to shutdown the machine & wait for few minutes and restarting the machine. Anyone have had experienced similar problem? I am suspecting the ACPI is triggering the machine to throttle.
I was able to replicate the problem and here is the temperatures the machine begun throttling
ACPI = 78C, Core 0 = 61C, Core 2= 72C, NVS 160 = 80C HDD = 45C
P8400 -> core speed = 1600MHz, multiplier = x6 bus speed = 266 MHz, FSB =1064MHz
BIOS = A11
